The Mastermind 套組：The Book、The Puzzle 與 The Playing Cards

The hand-illustrated book alone is worth it—I kept stopping to admire the detail on every page. The playing cards feel substantial and shuffle nicely, and the puzzle is just the right level of challenging without being frustrating. Finished the whole set over three evenings and my brain felt genuine

Spent a whole rainy Sunday with the puzzle and the cards, and the trio works perfectly together as a creative warm-up. The book's hand-illustrated guide genuinely makes you stop and think about how inventions and social systems connect, which is rare for this kind of set.

The illustrations in the book are what sold me—each page feels like a tiny museum exhibit you can hold. I’ve already spent two evenings with the puzzle spread out on the coffee table, and the cards are perfect for sparking late-night conversations.
